Carbon Steel I Beam

Carbon steel I beams are strong, cost-effective structural steel shapes used to support heavy loads in buildings, platforms, and industrial frameworks. Their “I” shape features wide flanges connected by a vertical web, providing excellent strength and stiffness.

I beam sizes are listed as two numbers, such as W10×33. The first number indicates the beam’s approximate height in inches, while the second number shows the weight per foot, which reflects the beam’s load-carrying capacity. As beam size and weight increase, the flange width also increases, helping resist bending and improve structural performance.
